Thanks to Mary, John's knowledge of Christ also increased. Mary, who had forgotten nothing of Christ's childhood, his familiar gestures, his way of being, had kept everything in her heart. These memories illuminated a specifically human personality, at least in appearance, for « a man is always a child for his mother. » Jesus, whilst being God, did not wish to escape this law. He wanted to owe his weakness and his fragility as a man, to a woman and a mother. Who better than Mary could testify? And yet, such was her testimony and such was she herself, that these human traits which could have discouraged John's faith in the divinity and form an insurmountable ordeal, were instead a source of enrichment and strength. The deeply human facts that he learned from Mary rooted him in his faith in Jesus Christ, the Son of God, and the Incarnation eventually became for him, through Mary, a totally positive reality.
